Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Altruism as a Signal of Status
Get PDFTitle: Altruism as a Signal of Status, Author: Greg Dingle, Location: ThodeFrom an evolutionary point of view, it is difficult to explain the existence
of altruism that is not directed at kin or at friends. But humans
demonstrate this form of altruism commonly, in such ways as donating to
charity or heroically saving another's life. One explanation of these
behaviours that is still consistent with evolutionary theory is the idea that
altruism may function as a signal. Altruists gain a positive reputation
through their deeds that may ultimately return to increase their biological
fitness. Here I test this idea in a variety of ways, focusing on altruism as a
signal of status. In the laboratory, I conducted an experiment where
participants had the incentive to signal their personal wealth to others. In
another experiment, I manipulated participants' relative status in an
attempt to reduce costly conflict between participants. Outside the
laboratory, I investigated the connection between heroism and
reproductive success through a sample of WWI heroes. The background,
methods, and conclusions of these studies are detailed within.ThesisMaster of Science (MS
Age-Specific Birth Rates in Brazil: Economic and Social Predictors of Reproduction by Adolescent and Adult Women
Get PDFTitle: Age-Specific Birth Rates in Brazil: Economic and Social Predictors of Reproduction by Adolescent and Adult Women, Author: Sarah Goodwin, Location: ThodeFor those who have reason to doubt the certainty or quality of their futures, it may
be adaptive to engage in an accelerated life course and reproduce earlier than the public
health policy officials consider ideal. This hypothesis was examined using life
expectancy, school registration, income, income inequality, and the degree of
urbanization to predict the birth rates of 15-19 year olds across municipalities in Brazil.
To evaluate whether adolescents respond differently to these indicators than older
women, the results for 15-19 year olds were compared to those obtained for women 20-
29, 30-39, and 40-49 years old. Negative binomial regression results indicate that
although teenage women seem to be the most sensitive to these socioeconomic indicators,
older women adjust their reproductive efforts in a similar manner. More specifically,
higher birth rates in all age groups are found in municipalities with short life
expectancies, lower rates of school registration, lower average incomes, and higher
income inequality. The degree of urbanization predicts differential effects according to
age; for the 15-29 age group it is positively associated with birth rates and for the 30-49
year old women it is a negative predictor. Repeating the analyses within the five Major
Regions of Brazil yields directionally consistent relationships for all predictors compared
to those for the country as a whole.ThesisMaster of Science (MS
Factors Associated with Hamilton, Ontario Women's Marital Surname Change Attitudes
Get PDFTitle: Factors Associated with Hamilton, Ontario Women's Marital Surname Change Attitudes, Author: Melanie MacEacheron, Location: Thode132 female, never-married, undergraduate psychology students were surveyed
regarding attitudes concerning taking their husband's surname upon marriage. It was
hypothesized that approval of such a surname change would be associated with their views
on (1) resource transfer from, and involvement with, in-laws, and (2) the importance of
high resource potential in a candidate husband. Lesser approval of taking husband's
surname was significantly predicted under OLS regression by desire for in-laws to be
uninvolved with the newlywed couple and their children. The importance of resource-holding
potential in a candidate husband was a marginally significant predictor, moderated
by the women's own mothers' taking of their fathers' surnames, as well as by how
emotionally close these women were to their mothers. Retaining or hyphenating one's pre-marital surname among brides marrying in
Hawaii in 2006, was significantly correlated with average income of women and the
average income of men in the bride's state of residence, with only that of women,
however, being a marginally-significant predictor where both were used as regression
predictors of retention or hyphenation. Older brides were more likely to hyphenate or
retain their pre-marital surnames upon marriage in Hawaii in 2006.ThesisMaster of Science (MSc
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
